I have Windows Vista basic on my Dell computer. Several days ago my son was playing internet games. Shortly after he finished, an icon for Norton Anti-virus scan showed up on the desktop. It has installed itself as a program in install/remove programs. I have un-installed it two times over the past two days. When I rebooted this morning, it was installed again.
I run the free version of AVAST. It hasn't picked this up as malware, or spyware. I don't know why Norton is showing up. I've had this computer a year, and it came with McAfee.
Could you please tell me what is going on, if it's harmful, and if it needs to be removed, how do I do it?
Thank you in advance for your help.
